简要总结
Accurate preoperative prediction of risk stratification, treatment response, and survival prognosis in gastric cancer is important for improving clinical treatment decisions, prolonging patient survival, and improving patient quality of life. The purpose of this study is to investigate the performance of the multi-parametric magnetic resonance imaging (mpMRI) and Dual-/Muti-energy CT and photon-counting Detector CT(PCD-CT) in the diagnosis and management of gastric cancer.
